Preliminary Information

ing bit-check mode, the incoming data stream is analyzed
bit by bit contra a valid transmitter signal. If no valid
signal is present, the receiver is set back to sleep mode af-
ter the period T
Bit-check
. This period varies check by
check as it is a statistical process. An average value for
T
Bit-check
is given in the electrical characteristics. During
T
Startup
and T
Bit-check
the current consumption is I
S
= I
Son
.
The condition of the receiver is indicated on Pin IC_AC-
TIVE. The average current consumption in polling mode
is dependent on the duty cycle of the active mode and can
be calculated as:
I

During T
Sleep
and T
Startup
the receiver is not sensitive to
a transmitter signal. To guarantee the reception of a trans-
mitted command the transmitter must start the telegram
with an adequate preburst. The required length of the
preburst depends on the polling parameters T
Sleep
,
T
Startup
, T
Bit-check
and the start-up time of a connected
μ
C
(T
Start,
μ
C
). Thus, T
Bit-check
depends on the actual bit rate
and the number of bits (N
Bit-check
) to be tested.
The following formula indicates how to calculate the
preburst length.

The length of period T
Sleep
is defined by the 5-bit word
Sleep of the OPMODE register, the extension factor
XSleep (according to table 9),
and the basic clock cycle
T
Clk
. It is calculated to be:
T
Sleep
= Sleep
X
Sleep
1024
In US- and European applications, the maximum value of
T
Sleep
is about 60 ms if XSleep is set to 1. The time reso-
lution is about 2 ms in that case. The sleep time can be
extended to almost half a second by setting XSleep to 8.
XSleep can be set to 8 by bit XSleep
Std
to
’
1
’
.
According to table 8, the highest register value of sleep
sets the receiver into a permanent sleep condition. The re-
ceiver remains in that condition until another value for
Sleep is programmed into the OPMODE register. This
function is desirable where several devices share a single
data line and may also be used for
μ
C polling
–
via Pin
POLLING/_ON, the receiver can be switched on and off.
